Thank you for your interest in my photographs. All prints are made using an Epson r2400 printer using Epson K3 Ultrachrome pigmented inks. These inks are rated for archival use. The paper used is Epson Ultra Premium Presentation Matte paper, and upon request I can use Epson Radiant White Watercolor or Epson Velvet Fine Art. All of these papers are acid free and archival quality. All matting, backing boards, and tape are acid free archival quality.
